Understanding the sub-continuum-scale structures and interaction mechanisms is an essential step towards developing methodologies aimed at understanding and optimizing the macroscopic behavior of complex materials and at designing metamaterials with tailored properties. As the computational power at our disposal grows, researchers are able to study the microstructure and micromechanical features at virtually any resolution. However, even nowadays the typical time and length scales of engineering applications are beyond the scope of most fine-scale methods. In many cases, high-resolution microscale simulations have therefore been employed to calibrate or even derive continuum-scale models governing the macroscopic behavior of materials. This enables us to analyze existing material systems or to design (meta-)materials with extraordinary characteristics by incorporating information from the sub-continuum scale. While such scale-bridging concepts build on a long history of averaging and homogenization techniques, the recent availability of large datasets provides new opportunities and poses new challenges with respect to microstructure characterization and the spatial and temporal averaging of small-scale interaction mechanisms.

This symposium aims at bringing together researchers working on advanced analytical, numerical, and experimental techniques revolving around homogenization, coarse-graining, and upscaling methods for materials science applications. Researchers engaged in the development and/or application of scale-bridging techniques across all materials systems, including, but not limited to, crystalline, amorphous, granular, composite, as well as soft- and biomaterials, are invited to participate. Presentations focused on data-driven approaches, microstructure-based materials design strategies, comparisons between simulations at differing scales, and comparisons between simulations and experiments are especially encouraged. We also welcome contributions focusing on experimental techniques for microstructure characterization, statistical geometry of microstructures, and microstructure generation.
